Although they struggled throughout, driver Leh Keen (left) and tuner Greg Caloudas (GSC Motorsports) kept this 13-year-old Supra Turbo in the hunt for overall honors. In addition to intermittent clutch problems, they had to change a hub en route to Indianapolis the evening of day six. Caloudas tried the Supra underground (supraforums.com) and connected with Bill Hansen in St. Louis, who had a Supra in his driveway and invited the team to take whatever it wanted—never a good idea with racers: The donor Supra may still be sitting on jack stands. The Supra gets its go power via a T67 turbo upgrade kit from Boost Logic. Running 23 psi of boost, the Supra delivered 570 rear-wheel horsepower, according to Caloudas. Recognizing the pitfalls of the Rule of More, Caloudas dialed the boost back to 17 psi later in the week.
